Seneca · On the trials of travel
Letters 57.3
The gloom, however, furnished me with some food for thought; I felt a certain mental thrill, and a transformation unaccompanied by fear, due to the novelty and the unpleasantness of an unusual occurrence. Of course I am not speaking to you of myself at this point, because I am far from being a perfect person, or even a man of middling qualities; I refer to one over whom fortune has lost her control. Even such a man’s mind will be smitten with a thrill and he will change colour.
